Alright I'll describe what my bike is doing. Starts easy as pie, idles perfect, pulls like a raped ape down low, wheelies no prob. Then when you'd expect it to start jerking your arms off it stops pulling almost like there is a rev limiter. Then I shift to the next gear and it starts all over. It was fouling plugs so I went down to a 45 on the pilot and a 162 on the main jets from a 47 pilot and a 168 main. No change. Powervalve is brand new and works fine, timing is spot on. Less than 2 hours on a new top end. I ride enduro and elevation is anywhere between 0-300 above sea and I'm in Houston so lots of heat and humidity. All I can figure is it is either a bad CDI or jetting issue. Running 40:1 with Klotz and premium fuel. Stock pipe and silencer so I already feel like my bike is jetted on the lean side and it still acts like it is a bit rich. Thanks guys!
